Can any one suggest me how to get xsd:base64Binary data in the JavaEmbedding activity.I can do normal Java Embedding activity.But coming to my requirement
i have an element in xsd of type base64Binary and get it in java embedding activity as string or byte[] .I did as given below and by changing it values

How are you loging the values ? Did you check in the log ?
Java embedded activity will now show up its value in audit trial. Use addAuditTrailEntry() to print your values just like sop and then try to check the values.

Hi
I'm working on SOA 11.1.1.5 version.I have one temporary variable $gRXML which is created from the schema element.How can i get the variable data of $gRXML/Payloads/PDF/BASE64
in the java embedding activity.Please give me the suggestions.

I think you are trying get the value directly from payload, can you try to assign the particular value into a variable and then try to get that variable data in java embedded like the example i have provided you.
